Choose the correct answer from the options given below:

The water table in an aquifer extending over an area of 150 ha is dropped by 2.0 m. Given that the porosity and specific retention are 35 percent and 10 per cent respectively. the change in ground water storage should be equal to _____________

The location of three observation wells is as shown in the following figure. If the total head in Well-1. Well-2 and Well-3 are 20.8 m, 20.4 m and 20.6 m, respectively. then the hydraulic gradient should be _______________.

Figure

Two monitoring wells. 400 m apart. are located along the direction of groundwater flow in a 20 m thick aquifer. If the difference in piezometric head in the wells is 1.6 m and the hydraulic conductivity is 45 m/day. then the rate of flow per meter of distance perpendicular to the flow direction should be equal to _________________
